Plenty of cities’ subway maps have been reimagined in the style of the London Underground map. Cameron Booth, for example, has redone New York’s subway map in that style. But a map posted by a graphic designer named Sean to Reddit does the exact opposite: it reimagines the London Underground map in the style of New York’s subway map. Bringing the design language of Michael Hertz to Harry Beck’s sovereign territory is probably blasphemous in some quarters, but as a pastiche of the New York style? Cameron says: “Sean has absolutely nailed the New York Subway map style, and perhaps even improved upon it in places—I note with pleasure that all of his station labels are set horizontally, instead of the many varied angles used on the official NYC map.” His bottom line? “One of the best style mash-ups I’ve seen: technically excellent, well-researched and actually really informative. Wonderful!”

It’s available as a print on Etsy, because of course it is.
